SEWER CONSTRUCTION.

original application flied July 31, 1925, Serial No. 47,281. Divided and this application filed April 5, 1926. Serial No. 100,987.

This application relates to improvements in sewer construction and is a division of my similarly entitled co-pend'ing application Serial Number 47,281, filed July 31, 1925 The present application is concerned more particularly with a grating or guard for sewer basins, which will exclude entry to the basin. flOllllJhQ gutter oi material of a size greater than can pass through the openings in the grating or guard. At the present time material such tor instance as sticks, tin cans, and rags, are permitted entry to sewer basins from gutters, and such material renders the cleaning of basins more ditlicult than would otherwise be the case, and requires the cleaning of basins more frequently than would otherwise be necessary. The expense of cleaning basins is considerable and material permitted to enter basins frequently causes the stoppage oi pipes which connect the basin with the sewer.

Another object of my invention is to provide an improved grating or guard which is of unitary construction and provided with automatic catch devices for holding thesame in place and resisting the ready removal of the same, for instance by mischievous boys or anyone who might desire to remove the grating or guard to throw objects into the basin.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more par ticularly pointed out in the claims appended hereto. y

In the drawings, wherein like symbols refer to like or corresponding parts through out the several. views,

Figure l is a fragmentary perspective view showing a gutter and sidewalk with my improved device in lace;

Figure 2 is a vertical section taken on the line 2% in Figure 1;

Figure 3 is a fragmentary front elevation of a curbing with parts below broken away and with my improved grating or guard shown in elevation;

Figure l is a. fragmentary top plan view of my improved construction with parts broken away; and

Figure 5 is a vertical section taken on the line 5--5 in Figure 3.

Referring more particularly to the drawlugs, 24: designates a street or roadway, 25 a curb, and 26 a sidewalk In Figures 1 and 2 a cover 130 is shown as provided in or on the sidewalk. By raising this cover 150 entrance may be ellected to the basin 52 through an opening 131 to re move contents of the basin to repair the basin, or for any other desired purpose. l. be opening 125i 1s shown as made through the sidewalk and as directly above the basin 52. A ladder is shown as provided by which. a workman entering through the opening 131 may descend in the basin tor the purpose oi cleaning out the same or performing any other desired work.

A form of grating or guard 36 is shown as titted in an opening 37 in the curb 25. in this case entry to the basin from the gut ter is shown as through the curb opening and is designated as 200. The curb 25, at the sides of the opening 87, is shown as pro-- vided with recesses ell to receive the tree outer ends of springs 42, shown as carried by the grating or guard 36, the free ends of the springs being shown as oli'sct backwardly to enable them with greater facility to snap into the recesses all in the act of pushing the grating or guard 36 into place.-

The springs 42 are such as to maintain the grating or guard normally in its place, The grating or guard 36 is shown as provided with an arm 40 on either side. Said arms are intended to assist in holding the grat ing or guard 36 in place. As the grating or guard 36 rests in the curb, the curb will also assist in holding the grating or guard in place. The curb may be recessed to re-- ceive the arms 40 and the sides oi the grab ing or guard 36.

The grating or guard itsel'l is made up of an open-work structure. The drawings show the grating or guard as including spaced. horizontal bars with short vertical bars extending between the horizontal bars,

and with the ends of the upper horizontal bar curved down to the lower horizontal bar and meeting with the lower horizontal bar just inwardly of the arms 40. The opening 37 in the curb is shown as made to correspond with the shape of the grating or guard illustrated in the drawings. It will be understood, however, that the grating or guard may take other forms.

The springs 42 will automatically snap into the recesses ll when the grating or guard is pushed intoplace. These springs will be relatively strong so as to prevent the cover from being readily pulled out.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of my invention without departing from the spirit thereof.

What is claimed is 2-- 1. A sewer construction comprising a curb having an opening to the sewer, and provided With a shouldered socket about the opening and recesses spaced inwardly from the. shouldered socket, an open-Work guard removably fitted into said shouldered socket, and. resilient arms carried by the inner portion of the guard with the free ends ofi'set backwardly whereby to snap into said rccesses.

2. A sewcr construction comprising a curb having an opening to the sewer and shouldered socket at the mouth of the opening flush with the curb line, said curb also having recesses substantially square in cross section in the side walls of the opening oll'set inwardly from said shouldered socket, an open-work guard reinovably fitted in said shouldered socket flush with the curb line, and spring arms having one end secured to the guard and the other ends bent away from the guard and outwardly beyond the side edges oi the guard whereby to encounter the wall of the opening and to snap into said recesses when the guard is put in place.

In testimony whereof l afiix my signature.
